Bitwarden Public API - Retrieve members

Hi guys,

We are implementing the Bitwarden API into our web application. Everything works as expected except for one issue.

When I try to retrieve all members, the list of collections per member returns null. However, when I retrieve a single member, the collections do show up in the response.

My question is: is there supposed to be a difference in these responses, is this a bug in the Bitwarden API or am I doing something wrong?

Thanks in advance.
